Dokar Newton ta Biyu ya bayyana cewa idan ƙarfin da ke aiki akan abu ba sifili ba ne, abu zai fuskanci hanzari. Girman hanzarin ya yi daidai da girman ƙarfin gaba ɗaya kuma ya yi daidai da nauyin abu. Alkiblar hanzarin iri ɗaya ne da alkiblar ƙarfin gaba ɗaya.
Idan girman hanzarin yayi daidai da sifili, to lissafin dokar Newton ta biyu zai canza zuwa lissafin Dokar farko ta NewtonDon haka dokar farko ta Newton misali ce ta musamman ta dokar ta biyu ta Newton.
Dangane da lissafin da ke sama, za a iya kammalawa cewa girman ƙarfin, girman hanzarin. Akasin haka, girman nauyi, girman hanzarin. Alaƙar da ke tsakanin ƙarfi, taro, da hanzarin an fi fahimtar ta bayan an gudanar da gwaje-gwajen da suka shafi wannan. Wani gwaji da za a iya gudanarwa shine gwaji don hanzarta jirgin ƙasa mai motsi akan layin dogo ta amfani da taro mai faɗuwa cikin 'yanci. Yi amfani da timer timer don tantance saurin jirgin.

1. Ka tantance girma da alkiblar saurin abin bisa ga hoton da ke ƙasa!
Tattaunawa
An sani :
Mass (m) = 1 kg
Ƙarfin taurin kai (F) = 4 Newton
An tambaya : girma da alkiblar hanzari (a)
Jawab :
Girman hanzarin = 4 m/s2, alkiblar hanzari = alkiblar ƙarfin sakamako = zuwa dama.

An sani :
Mass (m) = 1 kg
Ƙarfin taurin kai (F) = 4 Newton
Ƙarfin gogayya na motsi (f)k) = 1 Newton
An tambaya : girma da alkiblar hanzari (a)
Jawab :
Girman hanzarin = 3 m/s2, alkiblar hanzari = alkiblar ƙarfin sakamako = zuwa dama.
